In the following three dimensional structure of $\mathrm{CH}_4$, the bonds are labelled as $W, X, Y$ and $Z$…

- X,Y
- W, Z
- X, Z
- W, Y
Solution

Here, normal lines $(-)$ always shows the groups, lying in the plane of the paper. Solid-wedge shows the bond projects out of the plane of paper and towards the observer. Dashed-wedge $(|||| \mid)$ also, shows the bond projecting out of the plane of paper but it is away from the observer.
